2) at thickness be 5 ~ 100mm steel plate on, centered by milling surplus line projection line a2, the open slotted eye I that width H is 0.1 ~ lmm made by line, centered by the outer edge line projection line b1 of part milling face, the open slotted eye II that width H is 0.1 ~ lmm made by line, draws projection marking-off plate;
3) fitted in the line face (3-1) of milling formed template and part milling face (1-2), process the edge (3-2) of milling formed template by the outer edge line b of part milling face (1-2);
4) projection marking-off plate and milling formed template are placed on support, the position of milling formed template is regulated with the open slotted eye II of the vertical direction irradiation projection marking-off plate of light E edge projection marking-off plate, the upper all luminous point F formed are positioned on the outer edge line c in line face (3-1) of milling formed template in the line face (3-1) of milling formed template to make light E, again with the open slotted eye I of light E along the vertical direction irradiation projection marking-off plate of projection marking-off plate, gauge point G is drawn in the position of the upper luminous point F formed in the line face (3-1) of milling formed template (3) by light E,
5) with scriber, gauge point G is connected successively on the line face (3-1) of milling formed template, mark part milling surplus line a1;
6) on milling formed template, process groove opening (3-2) i.e. milling formed template by the part milling surplus line a1 that the line face (3-1) of milling formed template is marked to machine.
The beneficial effect that the present invention brings is: this method makes projection marking-off plate by the outer edge line of projection milling part and milling surplus line, with light, the milling part outer edge line on projection marking-off plate and milling surplus line information projection are rule on milling formed template again, the method is without the need in part upper shed, the labour intensity reducing workman improves the working (machining) efficiency 30% of milling formed template, the machining accuracy of milling formed template can be improved simultaneously, reduce processing cost.
